Hair Salon, Hair Stylist Professional Hair Iron Ultrasonic Agent Penetration Accelerator nac IRON What is the "nac IRON" accelerator? Conventional perms and hair straightening treatments have caused many dissatisfactions and disadvantages, such as hair damage from strong alkaline agents and excessive time consumption. This ultrasonic iron "nac IRON" differs from conventional agent accelerators. It vibrates the hair with ultrasonic vibrations, allowing the agent to penetrate deep into the hair without alkaline swelling or opening the cuticles. Therefore, it is very effective for the penetration of perm solutions and treatment agents without damaging the hair.
